Study system: fringe-toed lizards. Fringe-toed lizards (genus Uma) are restricted to desert sand dunes and possess several specialized adaptations that facilitate efficient locomotion in loose sand, particularly their namesake toe fringes (Fig. (Fig.1). 1). Sand dunes are insular and mobile, are able to migrate tens of meters downwind per year, and are tightly linked to Cited by: Genetic diversity is one of the three fundamental levels of biodiversity, so it is directly important in conservation. Genetic variability influences both the health and long-term survival of populations because decreased genetic diversity has been associated with reduced fitness, such as high juvenile mortality, diminished population growth, reduced immunity, and ultimately, higher .

Loss of biodiversity is among the greatest problems facing the world today. Conservation and the Genetics of Populations gives a comprehensive overview of the essential background, concepts, and tools needed to understand how genetic information can be used to conserve species threatened with extinction, and to manage species of ecological or commercial by: Conservation genetics, evolution and distinct population segments of the Mojave fringe-toed lizard, Uma scoparia Article in Journal of Arid Environments.

Fringe-toed lizards are lizards of the genus Uma in the family Phrynosomatidae, native to deserts of North America. They are adapted for life in sandy deserts with fringe-like scales on their hind toes hence their common name. Lizards of the genus Uma have a brown and tan coloration that helps them to blend in with the : Reptilia.

The Coachella Valley Fringe-Toed Lizard (Uma inornata): Genetic Diversity and Phylogenetic Relationships of an Endangered Species Tanya L. Tre´panier and Robert W. Murphy Molecular Phylogenetics and Evolution Vol. 18, No. 3, March, pp. –,   Introduction. Genetic diversity is one aspect of biological diversity that is extremely important for conservation strategies (Kaljund and Jaaska ; Gordon et al.

).It is well known that preserving the genetic diversity of endangered species can significantly affect their long-term survival and evolution in changing environments (Frankham et al. ).Cited by: Globally, the total diversity of lizards is more than species.

They have the largest diversity of any of the reptilian group and make up more than half of all reptile species. The largest genus of lizards is a genus of iguana, known as Anola, which has more than species. Lizards are known to have evolved more than million years ago.

A study of genetic variation among individual Coachella Valley fringe-toed lizards found that populations in different areas of the Coachella Valley have begun to accumulate distinct genetic differences.
